View ec2_getIP
While you can get the public and private IP address of your Amazon EC2 instance via the AWS Console, it may be extremely useful to query it from anywhere you can make an HTTP request, such a shell script. The operation is really simple, just make a GET request to the following URL from within your EC2 instance:
Local IP:
Public IP:
I often use this feature to pre-configure services and update configuration files, as in EC2 you get a new IP Address each time you reboot

Classic program that prints strings based on results of using MOD function against a List
View CracklePop.scala
Write a program that prints out the numbers 1 to 100 (inclusive).
If the number is divisible by 3, print Crackle instead of the number.
If it's divisible by 5, print Pop. If it's divisible by both 3 and 5,
print CracklePop. You can use any language.
/// any number x where x % y is divisible by that number. We'll use that fact to match boolean patterns in Scala.
//// In Scala RePL, copy-paste the function first. Then use the function in a second call from the REPL.
def listEval( number: Int ): String = (number % 3, number % 5 ) match {

String array manipulations
View gist:783c39cbddaf65c5a4c261d9c9ab9ae0
Take note of length - it is used as a String[] property > strings.length AND as a method for a String
array element > strings[i].length().
public Map<String, String> pairs(String[] strings) {
Map<String,String> map = new HashMap<String,String>();
for (int i = 0; i < strings.length; i++ ) {
if (strings[i].length() == 1 ) {
Character first = strings[i].charAt(0);
